RAILWAY SIGNALING SYSTEM.

Specification of Letters Patent.

Patented Oct. 27, v190s.

Application filed- July 18, 1906. Serial No. 326,780.

To all whom it may concern:

Be it known that I, CARL J. SorrwARzE, a citizen of the United States, residing at Adrian, in the county of Lenawee and State of Michigan, have invented a certain new and useful Improvement in Railway Signaling .Systems, of' which the following is a full,

clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this s eciiication.

' My invention relates to rai way signal systems, and especially to systems for giving an alarm or signal at railway crossings on the approach of a train.

Prominent objects of the invention are, to provide a simple, practical and effective sys tem of this kind.

The system which I show herein for carrying out my invention is shown as applied to an electric railway system, although the invention is also applicable to steam railway systems.

- In the system shown herein, I pombine the signaling or alarm system with the trolley system in such a way that the latter is instrumental in automatically giving a signal or alarm on the approach of a car to a crossing or other desired point. A simple way of carrying this out is to provide one or more auxiliary orsignaling wires at the side of the trolley wire, and provide the usual trolley pole with a device or member adapted to engage said auxiliary wire or wires, and to connect the latter in circuit witha signaling device sucli as a bell, and if necessary, with suitable resistance devices to pass the proper amount of current through the signallng device. Thus the trolley in traveling along a trolley wire, will come in contact with the auxiliary wire before reaching the crossin and by closing the circuit therethrough, will sound an alarm at any desired point.

In the accompanying drawings, Figure 1 is a plan of a portion of a railroad track and a trolley system, together with a signaling system embodying my present invention; Fig. 2 is a view showing a trolley car and trolley and signaling wires, together with the circuit connections of .the signaling system embodying my invention; Fig. 3 is an elevation of a portion of the trolley pole and the trolley and auxiliary wires.

In Figs. 1 and 2 I have shown the rails or tracks 1, 1, crossing a roadway 2 at which the The trolley wire 3 is shown suspended by suitable posts 4-, 4 carrying arms 5, 5 to which the trolley wire 3 and auxiliary or signal w res 6, 6 are insulatingly secured ,by insulatlng supports 7, 7. The auxiliary-or signal wire-s 6, 6 are shown extended in opposite directions on opposite sides of the crossing and extend as far from the crossing as it is desired to have the signal given. Of course thesewires could be placed at any desired 3- location along the tra In Fig. 2 a trolley car 8 is shown mounted on the rails and rovidcd with a trolley pole 9 having a tro ley wheel 10 coming in contact with the trolley wire 3. aside extension conveniently consisting of a rolongation 11 of the trolley wheel axle. ihis extension 1 lis adapted to make contact with the auxiliary wires 6, 6, striking either one or the other thereof according as said extension is on one or the other side of the trolley wire 3. A wire or rod 12 is extended down from the extension 11 to a bracket 13 on the trolley pole 9. This is to prevent the pin or extension '11 from getting above the wires 6, 6 and striking the insulators ports and injuring the same.

The two signal wires 6, 6 are connected together by a conductor 14 which is connected in circuit with suitable resistance shown in the form of electric lamps 15, the circuit also including a signaling device in the form of a bell 16. The latter is connected with the rail 1 by a conductor 17 so that the trolley wire 3 is connected by the trolley wheel and pin 11 in circuit with. the resistance, bell and the rail, and power station, with the result that the circuit will be automatically closed by the trolley on coming in contact with one or the other of the signal wires 6, 6. When the car comes from one direction, one wire 6 will be, contacted with, and when the car comes from the other direction, the other wire will be made contact with. By having two wires in this way, the signalin will be The trolley pole 9 is provided with or sup-- done on the approach of the car tot ie cross ing coming from either direction, and will be.

discontinued in each case when the car What I claim is:--

1. The combination with track rails and a trolley wire of signaling conductors extending on opposite sides of said trolley Wire, a car traveling on said rails and having a trolley to engage the trolley wire, said trolley be ing provided with a side extension to engage the signaling conductors, and with a bracket extending laterally from the trolley pole a substantial distance from the upper extremity thereof, a guard Inember comprising a rod connected with the outer end of said side extension and with the outer end of the bracket and extending parallel to the trolley pole, and a circuit connected with the trolley wire and with the rails and including a signaling device.

2. The combination with track rails and a trolley wire of signaling conductors extending on o osite sides of said trolley wire, a

car trave ing on said rails and having a trol-' ley to engage the trolley wire, said trolley being provided with'a side extension to engage
